I am unsure of whether the 3 cups of water were for boiling the raw chicken breasts or for the soup. I added it to the soup and it was very thin, so I'm thinking that it was probably just for the chicken. I'm not really sure of the purpose of the ground flax seeds either .. They didn't blend well and just sit on the bottom of the soup. I think this has potential but next time I would leave out the flax seeds and water.
I made this recipe with boullion cubes instead of the powder, I used 2 and the broth from the chicken, making it 1 cup broth and 2 cups water. It was what I had on hand... anyway, it came out delicious!
